IMPROVEMENT IN MACHINES FOR GUMMING LABELS.

- Specification forming part of Letters Patent'lNo. 196,161, datedOctober 16, 1877 application filed August 18, 1877.

To all whom it may concern:

Be it known that I, LAZARUS MoRGENTHAU, of the city, county, and Stateof New York, 11. ve invented a new and Improved Machine for GamingLabels, of which the following is a specification:

In the accompanying drawing, igure 1 represents a vertical longitudinalsection of my improved machine for gumming labels, and Fig. 2 is a topview of the same.

Similar letters of reference indicate corresponding parts.

The obj ect of this invention is to provide for the trades an improvedmachine for the purpose of supplying labels of all kinds, stamps,strips, printed matter, or anything else,whether made of paper, linen,silk, or any other substance, with glue, paste, mucilage, or otheradhesive substance, ,to be then attached to the objects for which theyare intended.

The machine puts on the adhesive substance in uniform, rapid, andeconomical manner, without in the least smircln'ng the face of thelabels or other articles. It maybe made of difierent sizes, according tothe purposes for.

which the machine is designed, and may also be employed with equalfacility for moistening stamps or other articles having gummed backs byrmming the machine with water in place of an adhesive substance.

The invention consists, essentially, of an endless feed-belt, thatconducts the labels to be gummed to an endless supply-belt, to which theadhesive substance is fed from a suitable receptacle below bydistributing-rollers. A circular brush exposes all parts of the label tothe ac tion of the supply-belt. A second revolving brush clears thelabels from the pressure-brush, and conducts them to an inclinedclearingplate, and from the same to the place of use.

By reference to the drawing, A represents an endless revolvingbelt, thatis stretched over suitable rollers, and passes over a slightly-inclinedtable, the belt being made of silk or other material. The belt A isintended to receive the labels, strips, stamps, or other sheets to begummed on the back, and feeds them face uppermost to a secondendlessbelt, B, that revolves on stretching-rollers, and passes over ahorizontal table. The second endless belt B is made of leather or othersuitable material,

and serves to supply the paste, glue,muoilage, or other adhesivesubstance to the labels. The supply-belt B receives the adhesivesubstance from a reservoir, 0, below the same, said reservoir having alateral screen, 0', to prevent any coarse impurities from passing to thedistributing-rollers D, of which the lower turns in the adhesive liquid,while the upper forms contact with the same and with the supplybelt B,and transmits thereby the quantity received to that portion of theendless belt B in contact therewith. The reservoir 0 is also providedwith a gage, a, by which the quantity of adhesive liquid in thereservoir is indicated at any moment, and the same refilled as required.

When the machine is to be worked with glue, the reservoir is heated upin suit-able manner to keep the glue in liquid state. As the labelpasses from the feed-belt A to the supply-belt B it is uniformly presseddown upon the latter by a circular brush, E, that slides in slottedstandards E, and revolves by the friction with the labels. Every part ofthe label or sheet being thus pressed upon by the brush receives auniform coating of adhesive substance from the supply-belt, which movesthe labels forward toward the end of the same, when they are lifted andcleared from the supply-belt B by a hinged and inclined plate, B, thatmay be readily thrown back when the belt is to be removed for cleaning.The inclined clearingplate rests, by its front edge, on the supplybelt,and secures the clearing of the labels in perfectly reliable manner, thelabels being then taken up by hand, or transferred to a conveying-belt,orto a labeling or other machine, or to the drying-racks, according asthey are to be applied directly to boxes, cases, bottles, or otherarticles, or to be dried, as in the case of postage and revenue stamps.

As the pressure-brush may take up some of the adhesive substance, andthereby exert on the labels a tendency to lap on the same, and

pass off from the supply-belt before they are taken up by the inclinedclearing-plate, a second guard-brush, F, with stiff wire or bristles, isarranged back of the pressure-brush, and its surface moved at point ofcontact in opposite direction thereto, so as to clear the labels fromthe pressure-brush, and secure their reliable forward motion on thegumming-belt, to be finally taken up therefrom by the clearingplate.

The motion of the belts and guard-brush .is produced by suitableintermeshin g gearing from a suitable driving-shaft, and the machineWorked either by hand or power, according to the Work to beaccomplished. Smaller machines, to be used in the trade for labelingbottles, cigarboxes, and other articles, may be readily worked by hand,While larger machines-such as supply paste to sheets of largesurface-may be driven by power.

The machine produces the quick, clean, and economical gumming of labelsand other sheets, and is, on account of its simplicity and constructionand reliable Working, adapted to a variety of applications in the trade.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent l. A machine for gumming labels and otherarticles, consisting, essentially, of a revolving feed-belt, a revolvingsupply-belt, a reservoir for the adhesive substance, and device fordistributing the same on the supply-belt, and of a pressure-brush abovethe supply-belt, substantially in the manner and for the purposespecified.

2. The combination, with the revolving supply-belt and pressurebrush, ofa guard-brush, its surface at the point of contact moving in oppositedirection to the pressure-brush, to prevent the labels from lapping onthe press ure-brush, substantially as and for the purpose specified.
